> Periodic FlinkStateSnapshot cleanup causes repeated SavepointError events
> -------------------------------------------------------------------------
>
> Key: FLINK-40384
> URL: https://issues.apache.org/jira/browse/FLINK-40384
> Project: Flink
> Issue Type: Bug
> Components: Kubernetes Operator
> Reporter: liting liu
> Priority: Major
> Labels: pull-request-available
>
> {{When periodic FlinkStateSnapshot creation is enabled, active snapshot
> resources may be deleted while their status is still being updated.}}
> The operator repeatedly reports errors:
> io.fabric8.kubernetes.client.KubernetesClientException:
> Failure executing PATCH at:
> .../namespaces/<namespace>/flinkstatesnapshots/<snapshot-name>
> Operation cannot be fulfilled on
> flinkstatesnapshots.flink.apache.org "<snapshot-name>":
> the object has been modified; please apply your changes to the latest version
> and try again
> HTTP status: 409 Conflict
> Each conflict produces a SavepointError Kubernetes Event.
> The affected FlinkStateSnapshot CR is normally deleted shortly afterward, but
> its Event remains until the Kubernetes Event TTL expires. Therefore, the
> namespace may contain many SavepointError Events referring to
> FlinkStateSnapshot resources that no longer exist.
>
> {{How to reproduce}}
> # Deploy Flink Kubernetes Operator 1.13 or later with the FlinkStateSnapshot
> CRD enabled.
> # {{Create a running FlinkDeployment.}}
> # Configure periodic savepoints and retain only one snapshot:
> kubernetes.operator.periodic.savepoint.interval: 10s
> kubernetes.operator.savepoint.history.max.count: "1"
> kubernetes.operator.savepoint.dispose-on-delete: "true"
> then:
> # {{Wait for the first periodic FlinkStateSnapshot to reach COMPLETED.}}
> # {{Wait for the next periodic FlinkStateSnapshot to be created.}}
> # Inspect the Kubernetes Events
